I'm a strong believer in allowing anonymous comments. Many engaged and intelligent commenters on blogs who have unique and valuable things to say must necessarily post anonymously given the nature of their employment or other factors.
It does get very difficult to follow message threads, however, when everybody is anonymous. And 'anonymous' is the most regular poster on this blog. Perhaps anonymous posters could at least identify themselves by a couple of initials, even if they're not real, in the interest of keeping our conversations cogent.
I'm not going to block anonymous postings, because I want this blog to engage all opinions, even those from persons who would feel threatened posting their name here. But I do ask that 'anonymous' be used with a little more discretion than it is right now.
